Hi Squidge – I have also seen media reports about sparkling water being particularly bad for your bones and teeth. The reports were from many years ago and I have avoided it for years. When I started BSD in 2016 I wanted a replacement for the Baileys I drank when we went out and looked into it again. It seems that it is coca cola and similar drinks that are the real baddies and sparkling water is relatively benign.
This is a very good article looking at the research in 2015 – http://www.bbc.com/future/story/20150911-is-sparkling-water-really-bad-for-you
So once or twice a month I have a lovely glass of sparkling water with a slice of lemon as a special treat plus my coffee and cream when we are out. Probably the slice of lemon that flavours the water slightly might erode my teeth – but as I don’t squeeze it and only have a couple of glasses a month I am not at all worried drinking it.
I really look forward to my glass of sparkling water and it is so much better for me than the Baileys.
